yes. i think. it seems that the books are in pdf format, so presumably they would work fine. but, i don't know if they have screwed around with the files with funky drm (digital rights management) restrictions, or something like that. they are surprisingly opaque about their service. i have never heard of anyone using them.
they may be a great company, but i would look into it more just in case. they are also shockingly expensive for some books that i searched.
